Halogenation of N-substituted p-quinone monoimines and p-quinone monooxime ethers: XIV.* halogenation of N-[arylsulfonylimino(phenyl)methyl]-2,5- dialkyl-1,4-benzoquinone monoimines and their reduction products

Avdeenko,Konovalova,Ledeneva,Santalova,Pirozhenko,Palamarchuk,Shishkin

, p. 928 - 937 (2012/11/07)

Despite steric hindrances created by the bulky substituent on the nitrogen atom, halogenation of 2,5-dialkyl-N-[arylsulfonylimino(phenyl)methyl]-1,4- benzoquinone monoimines fairly readily gives their derivatives having two halogen atoms in the quinoid ring. Pleiades Publishing, Ltd., 2012.
